Added a new flag -G to run. Setting -G (as in: go run run.go -G)
will run tests marked with "errorcheck" (and no other flags) also
with the compiler using the new typechecker.
Many tests don't pass yet (due to discrepancies in error messages).
The top-level tests in the test directory which don't pass yet have
been explicitly excluded, permitting to see the current status.
Future CLs will bring error messages in sync and eventually all
tests should pass.

This CL changes "T literal.M" error message to "T{...}.M". It's clearer
expression and focusing user on actual issue.

There were multiple ad hoc ways to create method symbols, with subtle
and confusing differences between them. This CL unifies them into a
single well-documented encoding and implementation.
This introduces some inconsequential changes to symbol format for the
sake of simplicity and consistency. Two notable changes:
1) Symbol construction is now insensitive to the package currently
being compiled. Previously, non-exported methods on anonymous types
received different method symbols depending on whether the method was
local or imported.
2) Symbols for method values parenthesized non-pointer receiver types
and non-exported method names, and also always package-qualified
non-exported method names. Now they use the same rules as normal
method symbols.
The methodSym function is also now stricter about rejecting
non-sensical method/receiver combinations. Notably, this means that
typecheckfunc needs to call addmethod to validate the method before
calling declare, which also means we no longer emit errors about
redeclaring bogus methods.
